Thank you for your help on this issue

Found the issue was incorrect location and missing items

 

Missing:

Alias=”blah.com”

Alias=”sip.blah.com”

 

The following was located in the wrong place.      

 

 

lookup("aliases");

    if (uri!=myself) {

    route(1);

    break;

    };

 

 

This needed to go after :

 

consume_credentials();

      };

 

 

 

Not after :

 

      if (uri=~"^sip:[+|00][0-9]*@") {  # International PSTN All other countries

       route(4);

      break;

      };
